Comparison of catalogues through asteroid observations

We have obtained 525 observations, made by four observatories between 1965 and 1989, of 16 minor planets to study the behaviour of the FK5 catalog near -30°. The minor planet coordinates to compare with the observations are generated by an n-body program that also integrates the major planets. The m...

description We have obtained 525 observations, made by four observatories between 1965 and 1989, of 16 minor planets to study the behaviour of the FK5 catalog near -30°. The minor planet coordinates to compare with the observations are generated by an n-body program that also integrates the major planets. The matrix of the equations of condition is 525 x 98. Because the resulting 98 x 98 linear system would occupy a great deal of memory, we have encountered a way to represent this kind of matrix, symmetric, positive definitive with fringes, that needs only 6% of the space required by a 2-dimensional array.
